Investopedia explains 'Collateral Trust Bond'
If the issuing company were to default on the debt obligation, the debt holders would receive the securities held in trust, like collateral for a loan.
For example, say Company A issues a collateral trust bond, and as collateral for the bond it includes the right to Company A shares held by a trust company. If Company A were to default on the bond payments, the bondholders would be entitled to the shares held in trust.
